TANK.

Application led 4September 2S, 1921. ISerial No. 503,885.

' To all lwhom t may concern Be it known that I, JOHN .W. KERLIN, a citizen of the United States, and a resident ofN ew Brunswick in the county of Middlesex and State of Ne'w Jersey, have invented a new and Improved Tank, of which the following is a full, clear, and exact description.

This invention relates to tanks and has for an object to provide an improved constructionwherein re in the tank or an explosion in the tank is rendered iin-possible or at least substantially impossible.

Another object is to provide a tank in which combustible and explosive material may be provided and at the same time protected against ire either continuously orl at intervals.

A still further object of the invention is to provide a tank in which the parts are so formed that one or more walls or sheets of water is provided around the tank for preventing explosion or burning of the contents of the tank.

In the accompanying drawings- A Figure 1 is an elevation of a tank showing one embodiment of the invention,' cer tain parts being broken away and shown in section for illustrating certain detail struc- 30 tures. Figure 2 is a top plan view of the structure shown in Figure 1, certain parts being broken away.

Figure 3 is a detail fragmentary sectional view through Figure 1 approximately on line'3-3.

Referring to the accompanying drawings by numeral, 1 indicates an inner tank of any desired kind which is provided with a vent pipe 2 having a bent over upper end 3 whereby any fumes or vapor from the tank may be readily prevented. The tank 1 ma'y be used to store `gasoline or any other substance desired and is preferably provided with a manhole 4 opposite the manhole 5 in the outer casing 6. A pipe 7 acts as a supply and also outlet pipe for the tank 1. This pipe, as shown particularly in Figure 3, is connected with a casting 8 bolted or otherwise rigidly secured to the tank 1, said casting having a`bore registering with the pipe 7 and with an aperture 9 in tank l.l A covering ring or disk 10 is bolted or otherwise secured to casting 8 and to part of the casing 6 whereby access ma be had to the space between the casing 6 an tank 1 at any time.

In addition to this means for permitting. access, a number of plates 11 are bolted o1" otherwise rigidly secured to the casing 6 in such a manner as to be readily removed for access to the space between the tank 1 and casing 6.

A thermometer 12 is arranged interorly of tank 1 and is connected with a suitable pipe 13 which extends to some signal mech'a- 65 plying the space b etween tank 1. and casing '70 6 with water and for causing a suitable overiow of thecasing. Preferably, however, a Signal isv connected with the ther- .mometer of pipe 13 'and water is manually turned on to the pipe 14 which is discharged 75 into the space between tank 1 and casing 6 as shown in Figure 1. This forms a wall of water surrounding tank 1 and said wall passes upwardly and over the top of tank 1 until it finally is discharged out the central 90 is flared over l top opening 15. Thisl opening so that the discharge will be substantially i even throughout and will fall on the top 16. An annular semi-tubular baiiie 17 is arranged on the top 16 a short -distance from the Vopening 15. Other bailies 18 and 19 are also connected with the top 16 to more evenlydistribute the water over the top and to 'cause it to fall in a comparatively even sheety over the outside of the casing 6 whereby fire cannot reach the tank 1 or heat cannot readily affect the same.

It will be noted that an inverted cupshaped member 20 is mounted above the opening l5 to protect the opening against the entrance of foreign lmatter and incidentally to properly direct the water from opening 15. In case the thermometer 12 gives an alarm, water may be turned on and the result will be a' comparatively thick wall of water surrounding tank 1 and an outside sheet'of water covering the top and sides of the casing 6. In case there` should be a ire near the tank or the temperature of the at'- mosphere should rise to an undesirable eX- tent' from the sun or4 other causes, water could be intermittently supplied to maintain the contents of the tank cool or below the danger point.

What I claim is 1. A tank of the character described comprising an inner container, an vouter casing spaced from the container, means for directl ing a cooling and fire extinguishing medium into the space between the container and the casing, said casing being open at the top for permittingsaid 4medium to flow out the top, together With'means to cause said medium to spread out evenly over the casing.

2. A tank of the character described comprising a container, a covering member therefor, means for directing water to the top of said covering member, and means for causing the water passing over the top of the covering member to ow in a substantially even sheet over the entire covering l member and container. 1

3. A tank of the character 'described comprising a container, a casing surrounding Athe container and spaced therefrom, said casing having a top spaced from the ltop of the container, said top having a centrally arranged opemng, means for directing water recense into the bottom of said casing so that it may rise,l in the space between the casingl and thev 4. A tank of thecharacter described coirnprising a container, a casing spaced from the container and covering the entire container on the top and sides, said casing being con nectedwith the container at the bottom whereby a space will be provided between the container and the casing except at the bottom, saidv casing having an opening centrally of the top, a plurality of annular arcshaped Water defiecting rings mounted lon said top, and means for directing water to the space between the casing and the container. r I
